This week has been especially chaotic for the Middle East. On Saturday, a Lebanese rocket killed 12 children and youth at a soccer game in the Israeli-controlled Golan Heights. (The victims were Syrian citizens with Israeli residency.) On Tuesday night, Israel took revenge for the rocket by killing Fuad Shukr, a commander in the pro-Iranian militia Hezbollah, along with two children.

A few hours later, a bomb killed Ismail Haniyeh, the head of Hamas' political bureau and the lead negotiator with Israel, while he was visiting Tehran for the Iranian president's inauguration. Israel is widely believed to be the culprit. Iran's Supreme Leader Ali Khamenei and Hezbollah leader Hassan Nasrallah have both promised to take revenge.

The same night that Shukr and Haniyeh were killed, U.S. warplanes rained down fire on an Iraqi militia base, killing four pro-Iranian fighters. An anonymous U.S. official told reporters that the militiamen were launching an attack drone that "posed a threat" to U.S. and allied forces. It was not clear whether the Iraqi drone was really aimed at U.S. troops—or Israel.

Soon it may not matter. The Biden administration affirmed again on Wednesday that it will help defend Israel in case of a conflict with Lebanon or Iran, as it did during clashes this April. And the administration has hinted before that it will get involved directly if Israel faces military setbacks in Lebanon. Israeli leaders may have been betting on exactly that outcome.

Unnamed "sources in the security establishment" told The Jerusalem Post that they could have assassinated Haniyeh in Qatar, where he usually lives. Instead, those sources explained, "the choice to carry out the assassination in the heart of Tehran was precisely because Haniyeh was under Iranian security responsibility, which placed Iran at the heart of the world's focus as a host, director, and supplier of terrorism."

In other words, killing Haniyeh was possibly meant to turn the Israel-Hamas war into an international crisis involving Iran and Israel's allies.

Months before the October 2023 attacks, Israeli policy makers had gamed out an Israeli strike leading to a U.S.-Iranian war. The Institute for National Security Studies, a think tank close to the Israeli government, ran a simulation in July 2023 that was eerily similar to the current escalation. The scenario began with an Israeli assassination campaign in Tehran, which provoked Hezbollah and Iraqi militias into attacking Israel and ended with direct U.S. attacks on Iran.

"Former top political and military leaders from Israel, the United States and a number of European countries took part in the simulation," reported the Israeli newspaper Haaretz.

For years before that, Israeli Prime Minister Benjamin Netanyahu and other Israeli leaders had been demanding U.S. support for an attack on Iran's nuclear facilities. It's not hard to understand why. Khamenei has called Israel a cancerous tumor that needs to be excised, and Israeli leaders have in turn said that Iran is the head of an evil octopus, which must be cut off.

The attacks on October 7, 2023, by Hamas seemed to confirm the Israeli perception. Whatever role Iran did or didn't have in planning the attacks—the U.S. government believes that Iranian leaders were just as surprised as everyone else—Iran's allies immediately jumped into the fray, attacking Israel in the name of the Palestinian cause.

And plenty of American politicians want conflict for their own reasons. Immediately after the October 7 attacks, Sen. Lindsey Graham (R–S.C.) had called for bombing Iran whether or not there was evidence that Iran was behind the attacks. On Wednesday, he claimed to have intelligence that "Iran will, in the coming weeks or months, possess a nuclear weapon" and introduced a bill calling for war with Iran.

A conflict with Iran also helps Netanyahu alleviate some of the domestic political pressure on him. Before the October 7 attacks, he was facing protests over his proposal to defang the Israeli Supreme Court. And instead of rallying Israelis around Netanyahu, the attacks galvanized opposition, as many Israelis blamed Netanyahu for the security lapse and the failure to rescue hostages.

This week, those tensions exploded into an outright mutiny. After months of international pressure regarding the treatment of inmates at the Sde Teiman prison, Israeli military police began a probe into one of the most egregious cases. Nine soldiers had allegedly raped a Palestinian prisoner so hard that he was sent to the hospital with a ruptured bowel, a severe injury to his anus, lung damage, and broken ribs.

Police detained some of the accused soldiers, and Israeli nationalists accused the government of betraying its troops. Nationalist rioters, including members of parliament, stormed both Sde Teiman and the Beit Lid military courts in support of the accused rapists. The army was forced to pull three battalions away from the Palestinian territories to guard the courthouse.

Killing Shukr and Haniyeh, then, was a good political bet for Netanyahu. At the very least, Netanyahu got to drown out headlines about the Sde Teiman riot with a dashing military victory. And if Iran hits back hard enough, then Israel may be able to get the world's superpower to fight Israel's greatest enemy.

But a full-on U.S.-Iran war would be a disaster for the region and for Americans. Gen. Kenneth McKenzie warned The New Yorker in December 2021 that Iran has missile "overmatch in the theatre—the ability to overwhelm" U.S. air defenses. American troops would face attacks in Iran, Iraq, and Syria, and a few well-placed Iranian strikes on Tel Aviv or Abu Dhabi could do serious damage to the world economy.

It would be a disaster of the Biden administration's own making. Soon after the October 7 attacks, President Joe Biden embraced the "bear hug" theory of diplomacy. By giving Israel public reassurances and unlimited military support, the theory went, Biden would earn enough goodwill from Israelis to keep their war contained and eventually broker an Israeli-Palestinian ceasefire.

Instead, the bear hug has turned out to be a sleepwalk. Netanyahu has taken U.S. support as a license to continue expanding the conflict. And the Biden administration seems to be at a loss for words about the latest escalation. Asked what impact the assassination of one side's chief negotiator would have on ceasefire negotiations, Secretary of State Antony Blinken played dumb.

"Well, I've seen the reports, and what I can tell you is this: First, this is something we were not aware of or involved in," Blinken told Channel News Asia. "It's very hard to speculate, and I've learned never to speculate, on the impact one event may have on something else. So I can't tell you what this means."
